I have the same issue where Alexa responds with "<devicename> is not responding"
Has there been any solution to this issue? The sonoff switch that is on 1.5 works. The newer one of 1.6 is not working correctly with Alexa. At first, it would not discover it. When it finally did it reported issues. Both work in the Ewelink app. I created an IFTTT command to control them as a workaround. Was getting ready to install a bunch of these in my mother's house this coming weekend. But if they dont work with alexa I will hae to pass.

It is working on app, but Alexa always says "<device name> is not responding".
I am getting crazy.
I did everything. I cleaned the devices, reinstalled the application, removed the Alexa connection with eWelink and did it all again.
15 minutes is enough to show problems.
Works on App and Alexa says that device is not connected.
Go back to the app to turn the lights. The voice command is not allowed.
